T @ZZ whom, it may concern.-

Beit known that I, EDWARD NELSON, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Trapping-Ma-4 chines, of which the following is a specifica- My invention relates to improvements in wrapping-machines for folding the necessary wrappers upon cakes of soap, candy, or other material; and it consists particularly lin providing new means for feeding the strips of wrapping-paper into the machine and cutting the same off into sections of proper size and new means for feeding the cakes of the material up to the wrapping-point and carrying them therefrom after being wrappedtoward the discharge end of the machine; also, in providing folders of new and peculiar construction and adjustment, new means of bringing said folders into action on the package, so as to make the various required folds of the wrappers, and new means of withdrawing the respective folders after they have been operated.

In the accompaning drawings, Figure 1 is a general elevation of the front or feed side of the machine, with some parts removed for greater clearness and others shown in vertical section. Fig. 2 is an elevation' seen from the side ofthe machine opposite to that shown in Fig. 1,with parts not immediately involved removed and others in vertical section, showing the devices for feedingthe strips of paper into the machine. Fig. 3 is a detached elevation of the pivoted cutter-arm and stationary cutter shown in Fig. 2, with the cut-` ters in position occupied immediately after cutting the paper. Fig. 4 is a front elevation of the paper-cutters detached, with the support of the stationary cutter partly in section. Fig. 5 is a detached elevation of part of the cam-wheel and the friction-roller for actuatingthe paper-feed rollers shown from a diiferent point of view in Fig. 2. Fig. 6 is a detached front view of three parallel guiderods, shown in cross-section in Fig. 2, between which the strips of paper pass on their Way to the cutters. Fig. 7 is an elevation, seen from the left-hand side of the machine, of the pivoted cutter-arm shown in side elevationin Figs. l, 2, and 3. Fig. 8 is an elevation on thefront of the machine of parts immediately employed in drawing the paper into the machine.

Fig. 26 is a side elevation of a retaining-lever mounted on the side of the folding-table. Fig. 27 is a top plan view of the same. Fig. 28 shows the top-folders making the top folds of the wrapper. Fig. 29 shows the top end-folders completing the downward IOO erences to the relative location of various parts, the direction of movements, dac., will for convenience be based on this supposition, without, however, intending to limit the arrangement of the parts to the various positions indicated.

The machine is provided with a suitable frame, including sides l 2, a skeleton top 3, and cross rods or bars 4 5 6 7 8 9. The powershaft 10, driven by a pulley 1l, is mounted 'in the sides of the frame and carries a series of cams 12 13 14 15 16, which actuate either by edgewise contact or by means of lateral camtracks various vertically or laterally acting members, which in turn actuate the various mechanisms, as hereinafter referred to.

The means of -feeding the strips of paper into the machine and cutting them off in Suitable sections to form a Wrapper will 'first be described. (See Figs. 1 to l0.) The general object of the machine being to inclose each cake of the material in two wrappers, an inner and an outenone, both of which are applied simultaneously, two paper-reels 17 18 are provided, rotatably mounted in brackets 19 20, extending from the frame, the lower reel 17 for the outer wrapper and the upper one 18 for the inner wrapper, which is usually of less width than the outer one. Fig. 2 shows the course of the paper strips as they pass into the machine. From the reels they irst pass between horizontal guides 2l and feed-rollers 22 23, supported on brackets 24 25, extending from the frame. Said feedrollers are driven by the edgewise contact with roller 22 of a friction-Wheel 26, mounted on a bracket 27, said wheel 26 being driven by frictional contact with the lateral face of cam-wheel16. Friction-wheel 26 has aradial adjustment across the face of cam-wheel 16, saidV adjustment being elected by turning the knurled wheel or knob 27, which turns the screw 27h, which enters a threaded perfor-ation in the block 27C, to which the spindle of wheel 26 is secured. Block 27c is slidingly mounted on bracket 27 between guide-plates 27d, which extendV into grooves in the sides ot' said block and are secured to said bracket. By this means the length of wrappers cut by ther machine may be changed for differentsizedpackages. Rollers 22 23 are kept pressed together by theaction of a spring 28, and their tension draws the paper from the reels. In operation said. feed-rollers 22 23 are rotated continuously, while the operation of the devices for drawing the paper into the machine is intermittent, so that during the interval a 'slack in the paper develops, as shownin Fig.

2, sufcient to form a wrapper, so that when the tractiondevices operate there is no resistance from the rollers. Leavingsaid rollers, the paper passes through an opening 29 in the lateral face ot' a pivoted cutter-arm 30, hereinafter described, and thence between horizontal guides 31 on the frame, (shown in detail in Fig. 6,) where the cut end is held after each operation of the cutters projecting upward in readiness to be engagedby the traction devices, which will now be described. (See Figs. 1, 2, 8, and 9.)

The cam 14 on shaft 10 has on a portion of its periphery a sinuous cam-groove 32, which engages intermittently a pin or roller 33 on the end of a lever 34, pivoted about centrally to across-bar 6 of the frame. Said lever 34 is oscillated once from left to right and once from rightto left during each revolution of cam 14 and during the intervals is stationary. The upper end of said lever 34 is connected by a pin-and-slot joint to a 'feed-arm 35, pivoted on a cross-bar 8 of the frame, a slot on the inner face of the lever engaging a pin on the outer face of said arm, or vice versa, so that said arm is oscillated by the movements of said lever. Near the upper end of said feed-arm 35 is firmly secu-red therein a crosshead 36, which extends inwardly at a right angle to said arm, partly across the machine.

\ Said cross-head 36 carries, pivoted thereto at its outer end, a soap-carrier har 37, to'be hereinafter described. It also carries the grippers 38 39 for seizing the cut end of the paper strips and drawing'them across the foldingtable 40. Said grippers are two in number, consisting of slightly-curved bills or prongs,

l flatten ed at the points, set opposite each other like the blades of a pair of nippers. The upper gripper 38 is rigidly attached to the crosshead 36 at the proper angle, so that when the cross-head isthrown toward the cutters, as in Fig. 2, said upper gripper will pass to the upper side of the edge of the paper 41, held in the guides 3l. The lower gripper 39 (see Fig. 9) is pivoted on the under surface of cross-head 36 on an integral shaft 42, rotatably mounted in suitable bearing-blocks 43. Said shaft 42 carries, rigidly secured thereto at its outer end adjacent to feed-arm 35, a depending trip-lever 44,130 which is attached a spring 45, fixed at its other end to arm35. The stress of said spring holds the grippers closed except when they are opened to receive the edge of the paper, which opening is effected while cross-head 36 is moving toward the guide 31, to the right in Fig. 2 or to the left in Fig. 8, by trip-lever 44 coming in contact with a stationary pin 46, projecting from the frame. The grippers are held open until cross-head 36 has 'completed its throw and the edges of the paper strips have passed between them. At this moment trip -lever 44 is released from contact withpin 46, and the `grippers immediately closeon the paper by the operation of spring 45. Feed-arm 35 then begins its return throw to the left in Fig. 2

IOO

IIO

constructed and adjusted that .it wipes past pin 46 during the return throw of arm 35, j ust described. This construction and adjustment consists in making the trip-lever of springy material and forming a slight twist in it from end to end, the twist being shown as clearly as possible in Fig. 11. The adjustment is such that when the arm 35 moves toward the paper-cutters the forward edge of the trip-lever 44 strikes the pin 46 and is thereby held until it is carried past the pin. Vhen the arm 35 recedes, the other edge of the trip-lever lies in a plane outside of the end of pin 46, so that the pin strikes theinner side or face of the trip-lever, which slips past the pin by virtue of its elasticity.

The soap-feeding devices are illustrated in Figs. 1 and 7 and 1l to 16. The cake of material 47 is delivered to the machine through a chute 48, supported on a bracket 49 at the side of the machine. The carrier-bar 37, as before stated, is pivoted to the rear end of cross-head 36 and is therefore oscillated longitudinally across the machine simultaneously with said cross-head. Said carrier is preferably a liattened bar rectangular in cross-section, as shown in Fig. 7. Its under edge is of irregular outline, having a'curved recess 50 near the pivoted end to prevent contact with the cutter-head and widening out in rear of said recess to provide space for the attachment of the parts forming the soappocket. The outer end of said rod is guided and supported'ina vertically-slotted bracket 51, extending upwardly from the movable cutter-head 52. The upper end of the slot in said bracketr see Fig. 7) is closed by a pin 53 or otherwise to prevent bar 37 from being thrown out of the slot during its movements.

The soap-pocket is attached to bar 37 at such a point that when said rod is retracted to the limit of its throw to the left in Fig. l and momentarily at rest said pocket will be in alinement with feed-chute 48 iu position to receive a cake of material. Bar 37 carries la horizontal bracket 54, having a curved lower edge, and on the side toward-the machine a flat vertical face 55, which forms one side of the rectangular pocket. The inner end of the pocket is formed by the side of bar 37. The side of the pocket opposite the face 55 of bracket 54 is formed by a vertical angular plate 56, secured on bar 37. A spring 57, secured on bar 37 or plate 56 and bent laterally at a right angle across the opening of the pocket, holds the cake of material from slipping out of the pocket after being deposited therein. Said spring 57 is retracted to admit the material by contact with the side of chute 48 or a pin 58 thereon when bar 37 reaches its limit of movement to the left. The movable bottom 59 of the pocket consists of a flat plate of irregular form pivoted v36, carrier-bar'37, tbc., to the right.

its outer edge contacting with a stop 61, extending from the cutter-head 52, which is at that time stationary. The rotation of said plate in either direction is limited by a stoppin 62, set inthe under surface of bracket 54 within a notch 63, Fig. 16, formed in the outer end of said plate. The cake of material being in position in the pocket is carried into the machine by the movement of cross-head The first result is to release spring 57, so that its bent portion will lie partly across the hither to-open end of the pocket and hold the cake therein during the subsequent movement.- The pocket first slides along the upper surface of the cutter-head 52, after leaving which the upwardly-curved under edge of bracket 54, moving over the front edge of said cutterhead, permits the pocket to settle to the level of the table. As the pocket approaches the folding-point immediately over the slot in the front end of table 40 a recess 64 in the bottom plate 59 contacts with a stationary pin 65 on the table and rotates said plate backward from under the cake, so that the cake drops from the pocket upon the paper already deposited on the table, as before de-` scribed. The next operation is lthe advancement of the cutter-head 52 to -cut 0E the wrapper from the strips to which it is still attached, and the cutters will now be described. (See Figs. 1, 2, 3, 4, and 8.) The ,stationary cutter 66 consists of a serrated blade secured on theframe and set vertically across and below the path of the paper after it has passed through the guides 31, between said guides and the folding-table. y The movable cutter 67 consists of a similarly-serrated blade fixed on the front edge of the cutterhead 52 above the path of the paper. The cutter-head consists of a suitable plate to support said cutter and is carried on the upper end of the bent cutter-lever 30, pivoted on the frame at 68. Said lever carries at its lower end a roller 69, which engages an an- IOO IIO

gular projection 70 on the periphery of camwheel 16 once with each revolution of said wheel. When the cutter-head is carried forward by the action of said cam, the teeth of the cutters are brought into intimate engagement with each other and afterward pass each other, as shown in Fig. 3, the paper meanwhile lying between them, and the paper to form the wrappers is severed from the strip,

leaving the wrappers lying one over the other,

bar 37, through the vertical slot in bracket 5l. Said lifter 7l consists of a slender metal rod or plate bent twice, so as to form an angle 72, adapted to engage a transvere pin 73'near the bottom of the slot in bracket 51, As shown in Figs. 13 and 14, the carrier-bar 37 during its feeding-in throw (to the right) draws the lifter after it through said slot, the cutter-head being stationary, and when the bar has reached theend of its throw said lifter will occupy the position shown in Fig. 15. The cutter-head then begins its advance, elevating bracket 51, and pin 73 contacts with the angle 72 in the lifter, pushing up bar 37. The lifter is rotated backward through the slot onY pin 73 as a pivot and when the cutter-head" has reached the limit of its advance movement will stand about vertically in the slot. At this stage the pocket will have been lifted entirely clear of the cake of material,l and bar 37 is then retracted by the throw to the left; of cross-head 36, before described in connection with the paper-feed, the lifter 71 dropping out of engagement with pin 73 into inactive position, as in Fig. 12. The folding operation next occurs, its object being, first, to turn up from below a fold of the paper upon each side over the top of the package, the folders for effecting which will be termed the top-folders; second, to turn down from above a fold of the paper upon each end of the package, the folders for effecting which will be termed top end-foldersg7 third, to turn in from each side at each end of the package lateral folds, the folders for e'ecting which will be termed lateral end-folders, and, fourth, to turn up from below at each end of the package a final fold, the folders for effecting which will be termed bottom end-folders.

The topsfolders 7a 75, Figs. 1, 17, and 23, consist of substantially right-angular blades of sheet metal hinged in recesses upon each side of the slot 40 in the folding-table and are pushed up over the cake of material, carrying the folds of the wrappers 76 with them, by contact with the prongs 77 of a vertically-reciprocating forked post 78, mounted in guides 79, Figs. 2O and 2l, on cross-bars 6 8, and actuated at the proper moment by a lateral cam-track SO in cam-wheel14, which engages a Vpin 8l on the lower end of said post. Said folders are shown closed upon the cake of material in Fig. 18. Said folders are retracted at the4 proper moment, hereinafter stated, by the descent of post 78, which draws said folders after it by means of links 82, Fig. 17, connecting said folders and post. The one of said folders which operates first (number 74, as shown in the drawings) has, preferably,

Ythe two portions of its blade hinged together said top-folders have operated they remain in position in engagement with the package until all the `other folders have been operated. The top end-folders 84 85 for making the downward end folds on the wrappers are pivoted on the lower ends of a yoke 86, which straddles a bracket-arm 87, projecting over the folding-table at a right angle from a vertically-reciprocating post 88, which is actuated intermittently by alateral cam-track in cam-wheel 13 engaging a pin on said post. While the top folds before described are being made and during most of the other opera; tions of the `machine thus far mentioned, post S8, bracket 87, the., are in elevated poL sition, as shown in Figs. 1 and 17. As said top folds are being completed bracket 87 begins to descend, carrying yoke 86,.folders S4 S5, &c. Said folders are shown completing the end folds in Fig. 29. Said folders, Figs.

17'and 22, are hinged horizontally on the' lower ends of yoke 86 and consist of hat blades which hang downwardly and are provided at their upper margins with inwardly-extending flanges or tongues 89. When said folders are inactive, the vertical blades swing outwardly and are so held by springs 90, which bear against the flanges 89. When said end-folders are brought d own to the folding-point, their edges contact with the extending margins of the` wrapper and press them downward against the ends of the package. The flanges 89 on said endffolders impinge against the upper blades of the top-folders 7a 75, now lying in folded position overthe package, rotating said end-folders on their pivots against the stress of springs 90 and pressing their vertical blades firmly against the package, completing the top end folds.` When said end-folders Sa 85 are released from the package at a later stage of the operation, they are returned KCC;

to their normal open or flaring position, as in Fig. 22, by the action of springs 90. Before the release of said last-mentioned folders from the package the lateral end-folders 91 92 93 9i, Figs. 1,17, 1S, 23, and 30, are brought into action. Said folders are hinged vertically on reciprocating carriages 96 97, which slide in opposite, directions on ways 9S on bracket-arm 87. Said folders (see detail Fig. 19) are four in number, one for each corner of the package, and consist of substantially right-angular blades or wings provided with springs 99, so adjusted that the longer wings, which are to engage the margins of the paper, are made to normally swing outward, as seen in Fig. 23, the better to engage the margins of the paper, and when in action said wings are pressed inward upon the package against the stress of said springs by contact of the top-folders 74 75, which still inclose the package, with the shorter wings. End-folders 91 92 93 94 are shown completing the lateral end folds in Fig. 30. After being released from the package said lateral end-folders are retracted by the operation of said springs. Said lateral IIO end-folders are loweredto the level of the package by the descent/of post S8, bracket 87,

tbc., and immediately thereafter one set of said folders 91 94 is pushed against the package by the action of the eccentric cam 12,Fig. 1, elevating a vertically-reciprocating post 100, mounted in guides 100 on the frame, which post impinges on an irregularly-shaped block 101, pivoted in the frame at 102, which lever in turn pushes on a rod 103, pivoted to itat 104, which rod 103 is also pivoted to the folder-carriage 96. Simultaneously with the operation just described the other set of lateral endfolders 92 93 is pulled against the package by a rod 105, pivoted to folder-carriage 97, and also at 106 to a downward projection of block 101. Just before said lateral end-folders are brought into close contact with the package to complete their folds and before bracket 87 is elevated the top end-folders 84 85 are lifted from engagement with the package and out of the way of said lateral folders by the action of a lever 107, Figs. 17, 18, and 23. Said lever is of substantially righ t-angular form and is pivoted at 108 in post 88. One arm of said lever extends downwardly into the path of a projection 109 on the rotating block 101, by which said lever is actuated, as in Fig. 18. The other arm extends horizontally and passes through the vertical slot 110 in yoke 86. Said 'yoke has a vertical movement in grooves on bracket 87, being lifted to its elevated position on the bracket by the operation of lever 107, and, when said lever permits, falling to its lower position by gravity. It is held in'its lower position, so as to operate the top endfolders 84 85 when bracket 87 descends, by a bent latch 111 on the yoke, having a notch 112 engaging a catch 113, fixed on the bracket 87.

The upper extension of said latch passes over I the outer end of lever 107, projecting through slot 110, the outer end of said latch being movably held in a bridge-piece 114 on yoke 86. When the moment for lifting folders 84 85 arrives, lever 107, actuated as stated, first lifts latch 111 out of engagement with catch 113, and then bearing against the upper end of slot 110 lifts the yoke itself to the position shown in Fig. 18. This lifting of yoke 86 is merely sufficient to take folders 84 85 out of the way of the lateral end-folders, all said folders subsequently partakin g in the general upward movement of bracket 87, post 88, &c. All the folders thus far described being in the positions shown in Fig. 18, the bottom endfolders 115 116 are next operated. (See Figs. 18, 24, and 25.) Said bottom end-folders are hinged on a 4carriage 117, which reciprocates on a slotted track-plate 118, rigidly secured to the upper end of a vertically-reciprocating post 119, actuated intermittently by a camtrack 154 in the side of cam 15, by the action of which cam the track-plate, carriage, and the folders thereon alternately rise and fall. Said track-plate 118 is located immediately below the stationary cutter 66 and extends partly across the machine transverse to the path of the paper and parallel with but below the longitudinal slot 40a in the table 40. The

carriage extends under the table 40 and the folders are so located thereon that they project npinto or through'said slot. Said bottom end-folders 115 116 consist of two irregularly curved or bent blades, each pivoted, about midway of its length, to carriage 117, with the inner edge of one them, 116, lapping over the inner edge of the other, 115. Said overlapping edge carries a transverse pin 120 of greater length than the width of slot 401L in the table. The inner flange of the other folder 115 is provided with a spring 121, interposed between it and the carriage-body, the stress of which spring tends to throw said folders apart into the open position shown in dotted lines in Fig. 24. The wrapping process being at the stage last referred to, the blades 115 116, in open position, are projected up through slot 40a, one of them at each end of the package, by the elevation of carriage 117, as before described, and when transverse pin 120 on blade 116 strikes the under surface of table 40 at the margins of slot 40a the upper ends of said blades are forced inward against the ends of the package, carrying with them the bottom end folds of the wrappers and completing all the folds. Said folds are shown forming the final end folds in Fig. 31. Said folders 115 116, owing to the position of the various folds on the package, are now sufficient to hold the wrappers in place, and all the other folders are withdrawn. Those carried on bracket 87 are first lifted from the package by the action of cam 13, post 88, dmc., elevating said bracket. Top folders 74 75 are then lowered by the action of cam 14 drawing down post 78, connected to said folders by the links 82, and simultaneously with the latter movement the fullywrapped package still held between the blades 115 116 is carried along the table toward the discharge end by the operation of a carriage-reciprocating lever 1 22, hereinafter described. Folder-carriage 96 is retracted to inoperative position, as in Fig. 17, when the bracket 87 ascends by means of a stationary hook 123 on the frame engagingi a projecting pin 124 on block 101, rotating said block and pulling on rod 103. Foldercarriage 97 is retracted at the same time in the opposite direction by rod 105, pivoted on the lower end of block 101, pushing against it.

The lever 122, Figs. 1 and 24, which causes carriage 117 to reciprocate on track-plate 118, is pivoted at its lower end to a cross-rod 5 of the frame. It extends upwardly and passes through slot 118a in plate 118, and also through a slot 125 in an extension 126 of the carriage. Within said slot 125 are mounted transversely antifriction-rollers 127, between which the lever extends, so as to always bear against one of them. Said lever 122 carries on one side a pin or roller 128, which contacts with the peripheral edge of the' eccentric camwheel 15, being held in contact with said cam by a spring 129, secured at its outer end to a bracket 130 on the frame. In Fig. 24 the parts are shown in the positions occupied by IOO IIO

IIS

them immediately after the folders 115 116 have been brought into engagement with the package. Cam-wheel 15 now rotatingin the direction of the arrow, lever 122 is thrown to the position shown in dotted lines, drawing carriage 117, conveying the wrapped package, after it. The plate 118, carriage 117, and folders 115 116 continue in elevated position until lever 122 has reached the end of its throw, when they are drawn down to position shown in dotted lines by the action of lateral cam-track 15a on post 119, said folders falling to open position by the action of spring 121. Said lever and carriage are retracted at the propel' moment when permitted by cam 15 by the tension of spring 129. Carriage 117 is always in elevated position when moving toward the discharge and in lowered position when being retracted, and remains in lowered position until the time arrives for folders 1 15 116 to engage the package. The wrapped package is now left on the table in contact with the last of the row of packages which have preceded it. Such contact is sniiicient to hold the folds of the Wrapper in place at the outer end of the package after folders 115 116 are withdrawn; but inasmuch as the folds at the inner end toward the machine would otherwise spread and become loose when released from folder 116 means are provided to hold said last-mentioned folds in place until the following package is brought against them. Figs. 26 and 27 show the device referred to. A lever 131 is pivoted on one side of table 40, so as to move in a vertical plane. It has a downward extension 131a, bent inwardly and then again downwardly, so that its lower endwill lie in the path of a pin 132, extending from the moving carriage 117. An angular arm or stop 133, xed on said lever, extends part way across the table as far as the margin of slot 401, so that when in elevated position it will lie in the path of the wrapped packages passing along the table toward the discharge, in which position it is normally held by a spring 134, connected to the lever and frame. When v the carriage reciprocates toward the discharge, the pin 132 thereon contacts momentarily with the lower end of lever 131, depressingsaid lever against the stress of spring 134, the arm 133 dropping into a transverse slot 135,-provided for it in the table. During the continuance of such depression of said arm the margin of the vpackage passes partly over it, and when the arm is released by the disengagement of pin 132 and lever 131 said arm presses upward, owing to the tension of spring 134, against the bottom of the moving package,and as soon as the package has moved far enough said arm rises and its vertical outer face contacts with the inner end folds of the wrappers, as in Figs. 26 and 27, and so remains until the coming of the succeeding package. In this manner a continuous succession of wrapped packages in contact endA to end are moved on toward the discharge. The inner face of the angular arm 133 is inclined downwardly to prevent undue friction with the .packages passing overit.

To keep the packagesV in line, guides 136 (shown in Fig. 1) are provided, extending longitudinally along the extension of the table 40.

The operation of the various parts of the machine having been stated in connection `Awith the description of their construction, a recapitulation ot' the operation is unnecessary. `It is to be understood that while the description has followed as nearly as possible the order of the operation of the parts upon the material the operationsiirst described are taking place before those last described are completed, the parts'being so arranged and adjusted as to operate and cooperate at the proper Vmoment and in as rapid succession as possible. In the machine as shown a fully-wrapped vpackage is discharged with each revolution of the shaft.
